rant

so this is just kind of a rant so today my gf told me that a guy we know asked her to go to a metal show with him now he is not like a friend he is just a guy she went to school with last year she said that she didn't want to tell me because she thought it sounded like he was asking her out on a date but SHE SAID MAYBE and didn't find out if its a date so my fucking girlfriend might go on a date with another guy and i have no idea what to do
